A further object isi to provide improved tool Ioceting teinplets, together With nevel teinpiet hoiding means.

The forward motionv or" the machine is induced by gear 'T in mesh with gears 2l rotating shafts 22 which' also carry piniens 23Y inniesh with gears' 24, Said gears 24 rotate axies Carrying track wheels 25 on rails 28. lSaid gears 2t aiso tiet/e1 in a reci; 2T te prevent sleippingef track Wheels 26 en reits 28,

The rehitien between the forwerd motion ofV the; machine and the Vertical motion Ynfi' i rent 2 is such that the operation of rein 2 presses the trenches '7, contained in sucees.- site areas of e tehie which is hereinafter die scribed, threugh niateriztt to he punched 8, Withaut interrupting thefferwarrt mation et raising plunger38 and weight 39.

the machine. Said table consists of longitudinal supports 30 to which is attached plate 29 carrying dies 9. Said dies 9 are held in position by bars 33 shown in Fig. 5 and Fig. 6. Material to be punched 8 rests directly on dies 9 and is covered by templet 3l in which holes are located for punches 7 over said dies 9 in the positions in which holes are required in material 8. plet 3l is held in proper relation to kdies 9 in plate 29 by means of extensions to bolts 32 as shown in Fig. 5. rIemplet 31 contains the required arrangement of holes for the particular material to be punched. Plate/29, however, may also hold dies not required in this arrangement; but representing arrangements for other material and templets.

Punches 7 may be of various lengths, within the area of each operation of ram 2, thus requiring less pressure than would be required to press all of the punches simultaneously. As the forward motion of the machine carrying and operating ram 2 is continuous, it will be seen that during the period of time requisite after the ram in its downward movement comes in contact with the punch until the work of the punch is completed, the table described must itself conform to the forward motion of the machine and ram, which is provided for as follows: On two edges of the table are fastened racks 34, which engage with a tooth on each end of ram 2 shown in Fig. 4, at a position in the downward course of ram 2 and the forward travel of the machine, which causes the table to respond to the movement of the machine throughout the punching operation. As ram 2 recedes from the table the rack 34 is released from the tooth at each end of ram 2, and the table returns to its former position by means hereinafter described.

Attached to the underside of longitudinal pieces 30 of the table, are pieces 36 so formed that the table will return by gravity to its position of rest between the successive pressing operations of ram 2. Said pieces 36 are placed at intervals along the table in contact with rollers 35 which are a part of movable supports. These supports consist of a weight 39 Fig. 1 and Fig. 7, attached to plunger 38 which rests on water in cylinder 37, the latter being connected to cylinders 41 by pipes 40; thus communicating the pressure induced by weight 39, on said water, to plungers 42 in said cylinders 41. Plungers 42 hold the rollers 35 in position under pieces 3G of the table by means of connecting bars 43 and 44. The weight of the machine passing over the supports is sunricient to press down the bars 44 and rollers 35 thus forcing plungers 42 together and As the machine passes away from the supports, the latter are gradually released and return to their normal position under the table.

Said tem- The templet 31 and the punched material may be removed from the table, replacing the latter with unpunched material, by any convenient method, such as an overhead crane, covering the table and sufficient floor space for the purpose. Such a crane may be rendered more eflicient by the use of a magnet for lifting the templet, and material.
